David Heinemeier Hansson has fulfilled the promise he made early last week and has released version 3.0 of his creation, the Ruby on Rails web framework. The new release is a redevelopment of the Ruby framework and incorporates the concepts from Rails former competitor, Merb, as a result of the decision to merge the two open source projects in late 2008.
